简单代码：

public class LaunchActivity extends AppCompatActivity {    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_launch);        if (isGrantSDCardReadPermission()) {           //        } else {            requestPermission();        }    }    private boolean isGrantSDCardReadPermission() {        return PermissionUtils.isGrantSDCardReadPermission(this);    }    private void requestPermission() {        PermissionUtils.requestSDCardReadPermission(this, REQUEST_CODE_SDCARD_READ);    }    private static final int REQUEST_CODE_SDCARD_READ = 1;    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        switch (requestCode) {            case REQUEST_CODE_SDCARD_READ:                if (isGrantSDCardReadPermission()) {                    //                } else {                    Toast.makeText(this, "failure because without sd card read permission", Toast.LENGTH_SHORT).show();                }                break;            default:                break;        }    }}

public class PermissionUtils {    /**     * 是否有权限     *     * @param context     * @return     */    public static boolean checkSelfPermission(Context context, String permission) {        if (null == context) {            return false;        }        int per = ContextCompat.checkSelfPermission(context, permission);        return per == PackageManager.PERMISSION_GRANTED;    }    /**     * Check that all given permissions have been granted by verifying that each entry in the     * given array is of the value {@link PackageManager#PERMISSION_GRANTED}.     *     * @see Activity#onRequestPermissionsResult(int, String[], int[])     */    public static boolean verifyPermissions(int[] grantResults) {        // At least one result must be checked.        if (null == grantResults || grantResults.length < 1) {            return false;        }        // Verify that each required permission has been granted, otherwise return false.        for (int result : grantResults) {            if (result != PackageManager.PERMISSION_GRANTED) {                return false;            }        }        return true;    }    public static boolean isGrantSDCardReadPermission(Context context) {        return checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE);    }    public static void requestSDCardReadPermission(Activity activity, int requestCode) {        ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, requestCode);    }}

最后再附上需要动态申请的权限组，每组只要有一个权限申请成功，就默认组内其他权限申请成功了。

group:android.permission-group.CONTACTS    permission:android.permission.WRITE_CONTACTS    permission:android.permission.GET_ACCOUNTS        permission:android.permission.READ_CONTACTSgroup:android.permission-group.PHONE    permission:android.permission.READ_CALL_LOG    permission:android.permission.READ_PHONE_STATE     permission:android.permission.CALL_PHONE    permission:android.permission.WRITE_CALL_LOG    permission:android.permission.USE_SIP    permission:android.permission.PROCESS_OUTGOING_CALLS    permission:com.android.voicemail.permission.ADD_VOICEMAILgroup:android.permission-group.CALENDAR    permission:android.permission.READ_CALENDAR    permission:android.permission.WRITE_CALENDARgroup:android.permission-group.CAMERA    permission:android.permission.CAMERAgroup:android.permission-group.SENSORS    permission:android.permission.BODY_SENSORSgroup:android.permission-group.LOCATION    permission:android.permission.ACCESS_FINE_LOCATION    permission:android.permission.ACCESS_COARSE_LOCATIONgroup:android.permission-group.STORAGE    permission:android.permission.READ_EXTERNAL_STORAGE    permission:android.permission.WRITE_EXTERNAL_STORAGEgroup:android.permission-group.MICROPHONE    permission:android.permission.RECORD_AUDIOgroup:android.permission-group.SMS    permission:android.permission.READ_SMS    permission:android.permission.RECEIVE_WAP_PUSH    permission:android.permission.RECEIVE_MMS    permission:android.permission.RECEIVE_SMS    permission:android.permission.SEND_SMS    permission:android.permission.READ_CELL_BROADCASTS
